Basically, lilies are not high-maintenance. But if you have no idea of their needs, you can make mistakes and get into trouble in the form of your darlings becoming ill. Which diseases are more common and how can you prevent them?

Root rot is usually discovered too late

Stem base rot: waterlogging is dangerous!

In not uncommon cases, the so-called stem base rot occurs in lilies. It expresses itself in browning stems and leaves. These dry up and fall off. Eventually the plant dies. The cause is fungal pathogens.

Lilies that are kept in a pot as houseplants are particularly at risk. Waterlogging can quickly occur in the pot if the drainage is not correct or there are no holes in the bottom of the pot. Waterlogging increases the risk of stem rot enormously.

Botrytis elliptica - spots on the leaves

If your lily is affected by this disease (fungal pathogen), you can tell by the round, yellow to reddish-brown spots on the leaves. These increase in size and are favored by damp weather. Over time, the pathogen spreads to the stems until they break off.

Fusarium wilt - the most serious disease in lilies

This disease, which is caused by a fungal pathogen, is considered the most serious disease in lilies. An infestation remains hidden for a long time because: The onion is slowly hollowed out from below. Eventually the plant dies. The fungal spores survive in the soil and can affect newly planted lilies.

Viral diseases - faint patterns on the leaves

If your lily has been attacked by a viral disease - usually spread by aphids - you will recognize this by the faint mottled patterns on the leaves. In addition, deformities occur. As soon as you notice such things, you should dispose of the diseased plant (preferably burn it). Otherwise, other lilies in the area could also become ill.

prevent diseases effectively

  • choose hardy varieties
  • buy healthy plants
  • Avoid injury to the plant
  • choose loose, humus-rich soil
  • ensure good drainage
  • when planting, loosen the planting hole generously
  • water regularly but moderately
  • don't over-fertilize
  • Disinfect cutting tool

tips and tricks

An infestation of fungi on above-ground parts of the plant is less serious. Although the plant dies, its bulb survives in the soil and sprout again the next year.
